“People aged 60 and older make up 12.3 per cent of the global population, and by 2050, that number will rise to almost 22 per cent,” the UN’s Population Fund said in a statement.
The number of older persons is expected to double again by 2050, when it is projected to reach nearly 2.1 billion. The older population of the developing regions is growing much faster than in the developed regions.
The world’s older population continues to grow at an unprecedented rate. Today, 8.5 percent of people worldwide (617 million) are aged 65 and over. According to a new report, “An Aging World: 2015,” this percentage is projected to jump to nearly 17 percent of the world’s population by 2050 (1.6 billion).
Key facts. Between 2015 and 2050, the proportion of the world’s population over 60 years will nearly double from 12% to 22%. By 2020, the number of people aged 60 years and older will outnumber children younger than 5 years. In 2050, 80% of older people will be living in low- and middle-income countries.
Due to increasing life expectancy and falling fertility levels, the UN explained that for the first time in history, individuals aged 65 or above outnumbered children under five years of age globally. Moreover, by 2050, one in six people in the world will be over the age of 65 (16%), up from one in 11 in 2019 (9%).
Executive Summary. If current trends continue, the population of the United States will rise to 438 million in 2050, from 296 million in 2005, and 82% of the increase will be due to immigrants arriving from 2005 to 2050 and their U.S.-born descendants, according to new projections developed by the Pew Research Center.
Population growth is the increase in the number of people in a population. Global human population growth amounts to around 83 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7.9 billion in 2020.
Growing at a slower pace, world population is expected to reach 9.7 billion in 2050 and could peak at nearly 11 billion around 2100. The study concluded that the world’s population could reach its peak around the end of the current century, at a level of nearly 11 billion.
There were 703 million persons aged 65 years or over in the world in 2019. The number of older persons is projected to double to 1.5 billion in 2050. Globally, the share of the population aged 65 years or over increased from 6 per cent in 1990 to 9 per cent in 2019.
Since 1900, the percentage of Americans age 65 and older nearly quadrupled (from 4.1% in 1900 to 16% in 2019 ), and the number increased more than 17 times (from 3.1 million to 54.1 million).
What is an ‘ageing population’ — a definition. An ageing population is one where the proportion of older people is increasing. This is also known as ‘demographic ageing’ and ‘population ageing’.
A worldwide phenomenon According to the latest estimates, by 2050 there will be 2 billion people aged over 60 ( 22% of world population).
— “People 90 and older now comprise 4.7 percent of the older population (age 65 and older), as compared with only 2.8 percent in 1980. By 2050, this share is likely to reach 10 percent.”
The number of people across the world over 65 years old will triple by 2050, drastically altering some countries’ demographic make-up, according to a new report by the Pew Research Center. These demographic shifts may adversely affect economies, as more elderly people depend on working-age men and women.
